JOHN A. OLSON, OF DOWNERS GROVE, ILLINOIS.

WOODWORKERS SCRAPER.

SPECIFICATION forming part of Letters Patent No. 695,1 17, dated March 11, 1902.

Application filed November 18, 1901. Serial No. 32.719. (No model.)

To all whom it may concern:

Be it known that I, JOHN A. OLSON, a cit-izen of the United States, residing at Downers Grove, in the county of Dupage and State of Illinois, have invented certain new and useful Improvements in Voodworkers Scrapers, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part hereof, and in which- Figure 1 shows my said new woodworkers scraper in longitudinal side elevation. Fig. 2 shows the same in plan View. Fig. 3 shows the same in end elevation as seen from the scraper end. Fig. at shows the scrapers free clamping-bar in plan. Fig. 5 showsthe said clamping-bar in elevation.

Like letters of reference denote like parts.

The object of my invention is to produce a woodworkers scraper in which the scraperblade is firmly held close to its working edge for the purpose of preventing the chattering of the cutter, and thereby injuring the result of the work, and also to so arrange the parts of my said device that any piece of steel blade suitable for such work can be held in my device, also and at the same time to provide a convenient handle or holding mechanism for my said tool.

To attain said desirable ends, I construct my said new device in substantially the following manner, namely: I produce a handle a, having a reduced central body i and an-enlarged and rounded outer end part i, and a laterally-extended head h with a fiat face a,

inclined from the vertical and transverse to the vertical plane of the axis of said handle. The lower edge of said head is rounded at h to form a fulcrum or support, on which said instrument may be made to turn. Into the lower part of the face a is embedded a thick metal plate 6, held by a screw 0, having a slotted head and a nut (6, let into the wood, as shown. Said plate bis provided with threaded screw-holes, which register with those of a superposed plate or clamping-plate 6, through which pass the winged screws 9, which enter said screw-holes in the plate 1). Between said plates 5 and e is held the scraper or blade f, which is simply a thin fiat piece of steel of suitable quality whose edge is but a short distance from the low'edges of said clampingplates. The said bar 6 is made slightly c0nvex inwardly and so as to yield or spring to the action of the screws g for the purpose of holding the bladef very firmly, and thereby prevent all liability to chatter.

The handle a is grasped ate" with one hand and is pressed upon above and in front of the narrowed part 1', and the part 2" is raised or lowered to find the best angle at which the tool will work the most.

When delicate work is to be done, the edge of the bladef is so set relative to the fulcrum h that it may be made to rest and glide on the surface of the work and to thereby regulate the degree of work of the cutting edge of said blade.

The inclined tool-face a and the face of the fixed plate I) are in the same plane and on them rests the scraper-blade f. On the upper end of said blade f may also be placed a handlef, formed of a cylinder of wood, in whicha longitudinal saw cut is made to receive the top of said tool-blade.

What I claim is- The combination with a woodworkers scraper-handle having an inclined tool-face and a fulcrum on said handle, of an adjustable scraper-blade held by clamping-plates extending, longitudinally, beyond each side of said head and whereof one of said plates is held, fixedly, to said head and the other of said plates is held to said fixed plate by screws passing through the first plate and threaded into said fixed plate, substantially as specified.

JOHN A. OLSON.
